Answers

Answer 1

Answer:

Answer:

Acute angle.

Step-by-step explanation:

For an acute angle, the angles less than 90 degrees. In this triangle, all of the angles are less than 90 degrees.

Fellow person with an easy question here :)) Travis made a scale drawing of a horse fly. If the scale is 4 mm= 1cm, then what is the actual wingspan of the horsefly?

A: 6.4 cm

B: 5.0 cm

C:5.5 cm

D: 4.4 cm

Answers

The actual wingspan of fly is 5.5cm

Step-by-step explanation:

Given,

Scale of drawing;

4mm = 1cm

Ratio of mm to cm = 4:1

Wingspan of fly in drawing = 22mm

Let,

x be the actual wingspan.

Ratio of mm to cm = 22:x

Using proportion;

Ratio of mm to cm :: Ratio of mm to cm

$4:1::22:x\n$

Product of extreme = Product of mean

$4*x=22*1\n4x=22$

Dividing both sides by 4

$(4x)/(4)=(22)/(4)\nx=5.5$

The actual wingspan of fly is 5.5cm

The answer is option two.

The second option is the correct answer.

a seamstress has a piece of cloth that is 3 yards long. she cuts it into shorter lengths of 16inches each. how many shorter pieces can she cut

Answers

Answer

Find out the how many shorter pieces can a seamstress cut.

To prove

Let us assume that the number of shorter pieces cut be x.

As given

A seamstress has a piece of cloth that is 3 yards long.

she cuts it into shorter lengths of 16 inches each.

1 yards = 36 inches

Now convert 3 yards into inches.

= 3 × 36

= 108 yards

Than the equation becomes

16x = 108

$x = (108)/(16)$

x = 6.75

Therefore the number of shorter pieces be 6 .

She can cut 6.75 shorter pieces

Further explanation

The division operation is one of the basic arithmetic operations

Common signs used are $\displaystyle \boxed{:}$ or $\displaystyle \boxed{\slash}$

The division is written by placing the numerator above the denominator with a horizontal line between them or use a slash with the numerator's position and the denominator is parallel

The division is actually an iterative subtraction operation (as many as the number of divisors)

Division is the opposite of multiplying

The general form of division can be stated by:

$\large{\boxed{\boxed{\bold{divident:divisor=quotient+remainder}}}$

example:

7: 3 = 2 + 1

7 = dividend

3 = divisor

2 = quotient

1 = remainder

The form of division can also be expressed in terms of fractions

In the number above, the form of fraction obtained is the form of mixed fractions

$\displaystyle (7)/(3)=2(1)/(3)$

Mixed fractions consist of integers and ordinary fractions

Division operation statement:

"7 divided by 3 equals 2 remainder 1

Known

a piece of cloth that is 3 yards long

shorter lengths of 16 inches each

Asked

the number of shorter pieces that can be cut

Answer

Division operation statement:

"3 yards long divided by 16 inches*

$\displaystyle =~3~yards : 16~inches$

We convert yards to inches

One yard is equal to 36 inches

1 yards = 36 inches

so for 3 yards :

$\displaystyle (1~yard)/(3~yard) =(36~inches)/(x~inches)$

$\displaystyle x=(3~yard*36)/(1~yard)$

x = 108 inches

Division operation :

108 inches : 16 inches

= 6.75 pieces

Which mixed number has the same value as 3.75?A 3 & 1/2
B 3 & 5/8
C 3 & 3/4
D 3 & 7/10

Answers

I believe its C. 3 & 3/4 I hope this helps:)

C because 3/4 is 75 and you add the 3 so it is equal to 3.75

Please help. What are the coordinates of the outlier?A. (3, 3)

B. (6, 5)

C. (9, 10)

D. (10, 9)

Answers

the outlier would be 9,10
it differs from the other points. if you graphed out each point 9,10 would not correspond with the other points.

Tyler makes $10 per hour at his job.The function f(x)=10x gives the amount of money Tyler makes after x hours.Graph this function and give its domain and range.

Answers

You will have the points: (0,0) and (1,10) and (2,20) and (3,30) etc etc

Plot at least 2 of these points. Then draw a line through them.

Each point has an x,y pair such that the y value is ten times the x value

For example, if x = 2, then

y = 10*x = 10*2 = 20

so that shows how (2,20) is one of the points.

-------------------

The domain would be the set of positive whole numbers assuming Tyler can only work a whole number of hours. If partial time values are accepted, then the domain would be the set of positive real numbers. Negative x values are not allowed as Tyler can't work negative 3 hours for instance.

In a similar fashion, the range is the set {0, 10, 20, 30, 40, ...} incrementing by multiples of 10 if x is the set of positive whole numbers. If x is the set of positive real numbers, then y can be 0 or larger which sets up the range of y being the set of positive real numbers as well.
